Host Security Personal (HSP) not only password-protects files and folders, it also protects you from hacker attacks when you surfing the Internet. It allows you to specify which websites or IP addresses can be accessed so can be used to block unhealthy websites. It can also block popular instant messengers, such as MSN Messenger, Yahoo! Messenger, ICQ, and AOL Instant Messenger. HSP also restricts uses of local hard disks, CD-ROM drives, floppy drives, and removable disk drives so without your permission, people can't copy files from your computer, install programs in your computer, or play games with your CD-ROM. It supports FAT/FAT32/NTFS and works under Windows 2000/XP.
